Unstructured Mesh Movement and Viscous Mesh Generation for CFD-Based Design Optimization, Phase I

Metadata Updated: May 2, 2019

The innovations proposed by ResearchSouth are: 1) a robust method to automatically insert high quality anisotropic prismatic (viscous boundary layer) cells into any existing CFD mesh; and 2) a robust unstructured mesh movement method able to handle isotropic (Euler), anisotropic (viscous), and mixed element grids for CFD applications, particularly, CFD-based design optimization. ResearchSouth is proposing to develop efficient, design-oriented application software that will significantly impact the current practice of computational design and analysis of aerospace vehicles. The most overlooked?and arguably the most enabling?technical aspect associated with the rapidly maturing CFD-based design optimization is mesh movement, especially for high Reynolds number viscous flow applications. CFD analysis based on unstructured grid technology is becoming the preferred approach for flow analysis of geometrically complex configurations. However, in the area of mesh movement and viscous mesh generation, the unstructured grid arena has experienced near paralysis for several years. We are proposing research that will provide robust solutions to both of these challenges and, thus, will provide air vehicle designers access to the full potential of unstructured grid technologies for performing design optimization as well as highly efficient "what-if-and-reanalyze" geometric modifications.
